Razorock reknot

Rezdog gave me one of the aluminum Razorock synthetics replicating an old Rubberset brush.

The handle seems a dead-ringer. Obviously done CNC. Solid aluminum.
Heavy! Nice. I have had many of the old originals, but the weight and feel of this is more favorable as the ergonomics go, IMO.

Did not like the syn knot so I decided to go 2-band. Wrapped the bristles in duct tape and firmly clamped in a vise, yanked them from the adhesive (which was all was there. No plug/glue.
Drilled the middle with a 3/16 bit and then down-in with a forstner bit hand-to hand, so to speak. Cleaned-up with a Dremel-drum sander.
Perfect diameter for a VS 24MM.

So I have tossed the knot into a coffee cup with 2 teaspoons of Oxyclean for an hour and rinsed it good. Smelling better and blooming.

I know the 13mm's of depth ain't gonna get it. Figure I need at least 5 more plus at least 3 to hold some Goop yet. 7-8 mm's.

Don't want to mess-up the handle....Figure to pad it in the jaws of the lathe somehow and go easy. Eyeing some adhesive-backed fuzzy-half of some Velcro strips on the jaws. Any Ideeers?

Maybe some radiator hose? Or use a forsner bit to cut a hole a similar diameter to the collar or handle cut that in half and use a machinists vice to hold it and use your drill press. I’m assuming you have all those things since you have a lathe.

HEY! I have that! 3/4 heater hose would work. :gaah:
Thanks!

Sharp dudes (John) helping sharp dudes (Tom) is what this forum is all about. I had not even thought of hosing.

Many minds are always greater than one when problem-solving matters.

:tu

Once you have it all dialed in you can do mine too.
:-)

Nice to see some brushes being fixed up!
Those Rubberset handles were one of the greatest designs ever, IMO.
A little heft to a brush is what I like, too light weight and it slips from my fingers.
This is gonna be an awesome brush!

Didn't know they made one like that! Affordable too! Might be worth getting just to re-knot. Let us know how it turns out (and how you did it). I don't have a lathe but i like the idea of using a forstner bit.(though now i see they are out of stock. l hope they still make them.)

Well, a forstner bit works with wood and plastic, but not with aluminum.
Got it chucked up with some heater-hose strips. Ran pretty darn true!

Ran a big bit up-in about 1/2 inch..

No carbides around for ID, so old tool-steel. Went slow until all was leveled.
Plug went-in, but outer hairs would not. Back in the lathe again to take more out til it fit .
Wound-up taking over 2mm more til perfect fit. I usually use a dremel drum sander to oversize wood brushes. Just did not know how much I was taking out. Just wanted it to fit! ;)

Nice, snug fit. Can move it fairly easy. It is also nice to be able to tilt it a bit as I like it.
I will bring one of my faves up tomorrow and play with the loft and compare before gooping it in.

Lookin nice Tom.
Well bored and sits pretty.
Heater hose good idea..

Awesome!
Out of my realm of skillset and tools, really cool to see done.
I think you're gonna have guys PM you on that.

I becha Rezdog has one on the way!
It does seem they are scarce right now.
They have some resin ones I bet a Forstner bit will work on.

In retrospect, if a 22-23mm drill bit was run into the bottom to accommodate a 22mm plug and adhesive, the rest of the ID would be perfect. Doing that would be a simple operation instead of oversizing it all for a 24mm. Perhaps. Still might not be deep enough.
It seems you don't just simply reknot some factory-made brushes.
They are not all like custom handles.

Think I should stamp a '5' on the barrell? :hmmm:

Looks to be sitting just about right in my opinion. Nice job Tom, and thanks for sharing the pics.

Yeah...That's about where it's going to wind-up.
Ought to goop it up right now! :D

Quite the nice vintage metal lathe to boot Tom. :beer1:

Yeah...Old South Bend. Runs on an accessory v-belt/leather belt drive.
Was likely run from the ceiling at some point. Old!

So I brought my HarryWally brush with the same knot in it to the shop.
I like where I set it, so will do same on this one.

Lots use epoxy, but I like to use Goop. No mixing or mess, a glob down in the handle and another on top of the plug. Shove it in and get it how I like it.
Hung-up to cure for a few days.

Fin!

Sweeeeet!

Do you do anything to scuff/roughen the metal to make it bond better or is that unnecessary?

Never have. None have loosened so far..

What is this Goop? I hate 2 part epoxys. Messy!

Goop! Been around for at least a couple decades.
We used to put it on our shoes for skate boarding.

Never thought about it for a knot glue, but I'll bet it works great!

Edit: it dries into a rubber material.

Sold in hardware stores, craft stores. Shoe Goop, marine, plumbing, household, automotive,etc.
All the same stuff. I tried to convince the guy at the hardware store of that.
He insists there are differences! :rofl2: There is also some 9000 uses something stuff at the Hobby-Lobby. Same thing.

Goop. Stinky til dried. Handy for lots of things!
Does not dry super-hard. Like rubber, I suppose.

Goop..

Used that many a time to fix a wet suit.

Yup...The old hip-boots! :D

Lmao! That's hilarious, I have purchased a few different Goop "types" over the years and was scratching my head wondering what the difference was!

I respectfully disagree slightly. Viva la differance!

Amazing GOOP® and Craft GOOP® contain a thinner formula for precise, detailed work.
Wood & Furniture GOOP® is a thicker, non-slump formula perfect for vertical and overhead applications.
Automotive GOOP®, Household GOOP® and Plumbing GOOP® are all the same formula.
Lawn & Garden GOOP®, Marine GOOP®, RV GOOP® and Sport and Outdoor GOOP® are all UV-resistant.
Shoe GOO® is a more rubbery formula allowing for greater flexibility.

Long live goop!

Maybe Goop was what Rubberset used or something similar.

That's a lot of Goop!!!

I still say it's all the same goop! :roflmao
That's the pitch the hardware man read....

Now, aeronautical and submarine Goop, I have admittedly not tried.
